Re: [ceph-users] CephFS small files overhead

2018-09-19 Thread Konstantin Shalygin
We are trying to use cephfs as storage for web graphics, such as thumbnails and so on. Is there any way to reduse overhead on storage? On test cluster we have 1 fs, 2 pools (meta and data) with replica size = 2     objects: 1.02 M objects, 1.1 GiB     usage:   144 GiB used, 27 GiB / 172 GiB

You need to re-deploy OSDs for bluestore_min_alloc_size to take effect. > On 4.09.2018, at 18:31, andrew w goussakovski wrote: > > Hello > > We are trying to use cephfs as storage for web graphics, such as > thumbnails and so on. > Is there any way to reduse overhead on storage? On test

You could probably cut the overhead in half with the inline data feature: http://docs.ceph.com/docs/master/cephfs/experimental-features/#inline-data However, that is an experimental feature. CephFS is unfortunately not very good at storing lots of small files in a storage-efficient manner :(
